“…The Obsessive–Compulsive Inventory‐Revised (OCI‐R; Foa et al, ; Peng, Yang, Miao, Jing, & Chan, ) was used to assess obsessive–compulsive traits, which contains six subdimensions (washing, obsessing, hoarding, ordering, checking, and neutralizing).

Higher scores on these measurements indicated more risk features.…”
